Description

Jejunum nutrition balloon dilatation tube for neonates

Technical Field

The utility model belongs to neonate nutrition supply equipment field, concretely relates to jejunum nutrition sacculus expansion tube for neonate.

Background

Congenital Esophageal Atresia (CEA) is a serious neonatal digestive tract malformation, the incidence rate is 1/4000-1/3000, and the natural fatality rate is extremely high. The infant must be treated by surgery as soon as possible after birth. Long-time venous nutrition is needed after the operation, and enteral nutrition is generally carried out after about the seventh day after the operation. Postoperative anastomotic stenosis is the most common complication of congenital esophageal atresia, and balloon dilatation needs to be repeated for many times, and patients who do not have the effect of repeated dilatation need to be treated by a second operation. After the operation of the infant, long-time fasting, venous nutrition and high-frequency saccule expansion not only have great negative influence on the postoperative recovery of the infant, increase the incidence rate of postoperative complications and increase the pain of the infant, but also increase great economic burden for the whole family. The conventional stomach tube can only enter the stomach, and nutrient solution is injected into the stomach tube in early stage, so that the nutrient solution in the stomach can easily flow back to the esophagus to cause serious infection, healing of an anastomotic stoma is affected, and residual fistula and even death are caused.

Aiming at the problems, the problem to be solved by the technical personnel in the field is to develop a nutrition delivery device which can effectively reduce the pain of the sick children, the incidence rate of postoperative complications and the economic burden of families.
